Changelog for update GOG-7 (Mac) (added 18 November 2015):

- We've updated the Mac installer for Resonance to be compatible with Mac OS X 10.11 (El Capitan)
- This update means that disabling the System Integrity Protection feature is no longer required.

- Updated all versions to newest stable AGS, so a lot of problems have been fixed. However, your saves will unfortunately break because of the DISPARITY between the AGS versions.
- Added proper LINUX and MAC ports!
- If you want to revert to the older Resonance and continue your current progress,

Here's a small guide.
1) Select Resonance, next to play select and then select configure.
2) Untick "AUTOMATICALLY UPDATE TO THE NEWEST VERSION"
3) Select the older version [there should be two, pick the bottom one]
4) And you're done!

- Here are saves in case someone needs em!
